I don't know them and cannot say that it is a scam, though some say it is. However, the claims made in this page about their course are bizarre.
Their course has some recognition, but is the Florida Department of Veterans Affairs really that impressive an organisation for accreditation worldwide? I sasw the article about them scamming, but am not sure whether to believe it. The ELT training scene is Thailand is exuberant, with many providers and the internet is full of rows and fights about the validity of the courses offered. It's really hard to pick out what it correct or wrong as there are so many claims and counter-claims. Thai ESL is a world unto itself.
However, none of the trainers offering their own courses has anything like the recognition and respect that the CELTA has. My advice to anyone starting today is to get that course. I looked at job adverts and it's clear what employers want:
Which ELT Qualification? - Tdol's English Language Blog
What's their cancellation policy?
PS I will ask someone who knows a lot about the specifics of Thai ELT training to come and post here.
